DEVICE FOR INCREASING THE EFFICIENCY OF FUELS.

To all whom t may concern:

Be it known that we, CAMILLE MAGNE, a subject of the King of theBelgians, and resident of 18 Place de la Villette,Marcinelle-Cl'larleroi, and EDOUARD DEMEURE, a subject of the King ofthe Belgians, and resident of 53 Avenue des Arts, Brussels, Belgium,have invented certain new and useful Improvements in Devices forIncreasing the Efciency of Fuels, of which the following is aspecification.

In the patent applicationfiled in the name of Camille'h/lagne, SerialNumber 361,725, dated March 11, 1907, there has been described a processfor increasing the efliciency of fuels, by feeding to fires, furnaces,hearths, or fire-boxes, etc., either mechanically or by chimney suctiona mixture of air and steam, or any other mixture of suitable proportionspreviously brought to a high temperature and into contact with theincandescent fuel.

rThe object of the present invention is to provide a device forintroducing this process into practice.

filhe device consists essentially in providing: 1st. One or morechambers in which taltes place a thorough mixing of air and steam orvapor. 2nd. One or more series of conduits or pipes in which takes placean active vaporization of the mixture so 0btained, which mixture entersunder the `firegrate.

One form of the invention is represented in the annexed drawings inwhich z- Figure 1 is a vertical cross-section of the apparatus on lineA-B of Fig. 2. Fig. 2

is a vertical longitudinal section of the ap-v paratus on line C-D ofFig. 3. Fig. 3 is a horizontal section of the device on lines E, F, G,H, of Fig. 2. Fig. l shows a mode of suspension for pipes.

Referring to the drawings :H1 is the iire grate.

2, 2 are steam pipes.

2', 2 are openings for the discharge of water of condensation.

3, 3 are chambers where the mixing of air and steam takes place.

4, l are series of tubes or conduits, which are heated by the radiationof the lire, and through which the mixture of air and steam, coming fromthe mixing chambers, flows.

5, 5 are plates in which the tubes 4 are suspended.

Speeicaton of Letters Patent.

Application filed March 22, 1907.

Patented Feb. 28, 1911. serial No. 363,945.

6, 6 are plates in which the lower ends of the tubes are inserted.

7, 7 7 are arrows showing the direction in which the steam moves.

`8, 8 8 are arrows showing the air entrances.

9, 9 9 show the directions in which the mixture of steam and air flows.

10, 11 and 12 are panels which form part of the casing of the device.

13 is the door of the lire-box and 14 th door of the ash-pit.

15 is t-he bridge-wall.

The form which has been represented by way of example in the annexeddrawings, shows a duplicate device applied to boilers. In this form,each half of the device is substituted for one of the side walls of thelire-box. Steam enters through the pipes 2 1n the mixing chambers 3. Airis admitted to the chambers as indicated by the arrows 8, through a slot18, as clearly shown in Fig. 1. It is advisable to direct the steam andthe air in such a way as to obtain a very active mixing. The mixing ofthe steam and air is brought under the fire grate through multitubularconduits of suitable dimensions. In the form shown in the annexeddrawings, these conduits are formed by means of series ofl metallictubes. The conduits may also be made of other lire proof material. .Inthe example shown the tubes are of small diameter and very close to eachother.

It will be noted that both the :mixing chambers 3 and the tubes 4f forconveying the mixture of air and steam beneath the grate, are alllocated within the walls of the combustion chamber and consequently aresubjected to the intense heat therein.

By our improved construction the natural chimney draft or suction issuliicient to effeet a proper delivery of the mixture of air and steambeneath the grate and a much more even feed obtained than by the oldmethod of forcing the mixture in the form of a blast. The latter methodalso tends to hasten combustion with a consequent waste of fuel.

The door 13 of the re box and the door 14 of the ash pit remain closedduring the working of the device.

Fig. 4: shows a method of suspending the tubes in which the tube 16 isprovided with a flange 17, by means of which it is susl 1"ffpendeld'nthe upper tube plate 5,'vrhile *it l is simply'inserted inthejlower tubular plate Y, 6..- This methodV of assemblingallows ofthesimultaneoususe of any other systems of f heat conservation.
